To all whom it may concern:

Be it known that I, JoRGEN JoRGnNsEN, a citizen of the Kingdom ofDenmark, and a resident of Copenhagen, Denmark, Baldersgade 8, masterblacksmith, have invented new and useful Improvements in Water-Purifying Apparatus for Feed-Water in Steam-Boilers, of which thefollowing is a specification.

My invention is an improvement in purifying apparatus for feed water,and relates especially to that class of purifying apparatus wherein thefeed water is mixed with lime water contained in a tank or vessel, thelime waterbeing supplied to the feed water at definite intervals.Referring to the drawings forming a part hereofFigure 1 is a front viewof the apparatus partly in section. Fig, 2 is a plan view, and Fig. 3 isa section on the line A-A of Fig. 1.

In the embodiment shown in the drawing, 1 is a casing in which ismounted a shaft 1, having secured thereto a water Wheel 1 The feed waterpasses into the casing through the pipe 1 and is delivered there-- fromthrough the pipe 1, rotating the said wheel in its passage. At 1, thedelivery pipe is provided with a funnel-shaped opening, through whichthe lime water is delivered into the said delivery pipe from a casing lto be presently described.

' An arm 2 is fixed to the shaft 1 of the water wheel,

and the free end of the arm is provided with a weight 3.

An elbow lever is pivoted to the casing adjacent to the shaft as at 8,and one arm 6 of the said elbow lever is adapted to be engaged by theweight, the other arm 9 of the lever being connected by a link 10 withone of the arms 11 of another elbow lever pivoted to the casing 1 beforementioned. The other arm 12 of the said elbow lever is adapted to engagea sleeve 18 slidable' on a lever 19 rigidly connected with the valvestem 21, of the valve 21, which controls the opening in the bottom ofthe casing l The sleeve 18 is provided on its lower face with a cam 18,for engagement by the arm 12 of the elbow lever, and the sleeve isnormally maintained in its outermost position by a spring 20 arrangedbetween the sleeve and a collar on the said lever. A cord 17 isconnected with the sleeve 18, and is wound upon a pulley 16 secured to ashaft 16* j ournaled in bearings 18 on the casing 1 and a second wheel15 is secured to the shaft upon which winds a cord 14 connected with afloat 13 adapted to be moved up and down in the casing by the lime watercontained therein.

A disk 5 is secured to the shaft 1, and the said disk is provided with apin 4 for engaging the arm 2, whereby to turn the said arm with theshaft, and the opposite end of the shaft is provided with a disk 5 towhich is connected a link 5 the said link being connected at its otherend with an arm 5, rigid with a shaft 5 extending across the casing land the said shaft has secured thereto pairs of arms 5 the free ends ofthe arms being connected by cross bars 5 for a purpose to be hereafterdescribed. The upper end of the arm 5 is provided. with a ring 5*?engaged by an arm 5 secured to the upper end of the valve stem 21.

In operation when the feed water is introduced into the casing 1 throughthe pipe 1 the water wheel 1 is rotated and with it the disks 5 and 5.The rotation of the disk 5 imparts an oscillating movement to the shaf t5 through the connection of the link 5 with the arm 5, whereby to causethe cross bars 5 to agitate the lime water in the casing, while throughthe connection of the arm 5 with the arm 5 the valve stem 21 is alsooscillated in order to prevent an accumulation of undissolved limearound the valve. The disk 5 in its rotation will carry therewith thearm 2 by means of the pin 4 engaging therewith, and once during eachrevolution of the arm 2 the weight 3 will engage the end 6 ol' the elbowlever, to move the same upon its pivot, which by means of the link 10and the elbow lever 11l2 will elevate the valve 21 to permit a certainamount of lime water to pass into the pipe 1 to mix with the feed water.If the casing contains a large amount of feed water, the float valve 13will be elevated, and the spring 20 will tend to force the sleeve 18 toits outermost position, so that the arm 12 of the elbow lever 1112, willengage said sleeve at the lowest part 0 the cam 18, and the valve 21will be elevated a minimum distance. When, however, the supply of limewater is low, the descent of the float valve 13 will unwind the cord onthe wheel 15, thus causing the cord 17 to wind up on the wheel 16, todraw the sliding sleeve inwardly, whereby to bring the higher part ofthe cam in position for engagement by the arm 12. This movement of thesleeve will cause a greater elevation-of the valve 21 and as aconsequence a longer opening of the said valve, so that a greater amountof lime water is admitted to the pipe 1 I claim 1.
